Attention for connect the circuit
F-6088
When BK3231 connect external amplifiers, it must connect differential input amplifier. If not, the module
must connect an op-amp to balance two difference levels; otherwise, it will appear the "snapped" impact
sound.
Statement:
A Wireless Bluetooth use environment: the wireless signal is widely influenced by the surrounding environment.
Such as the trees and metal can absorb certain wireless signal. Therefore, the transmission distance has been influenced in
the application.
B The Bluetooth Modules are supporting the existing system, placed in the shell. However, the metal
shell can shield the wireless frequency signal. We suggest not to equip-ed it in a metal shell.

A certified modular has the option to use a permanently affixed label, or an electronic label. For a permanently affixed label, the module
must be labelled with an FCC ID: KKI-F-6088. The OEM manual must provide clear instructions explaining to the OEM the labelling
requirements, options and OEM user manual instructions that are required
For a host using a this FCC certified modular with a standard fixed label, if (1) the module’s FCC ID is notvisible when installed in the
host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module
so that the FCC ID of the module is visible; then an additional permanent label referring to the enclosed module:
“Contains Transmitter Module FCC ID: KKI-F-6088” or “Contains FCC ID: KKI-F-6088” must be used. The host OEM user manual
must also contain clear instructions on how end users can find and/or access the module and the FCC ID.
Host product is required to comply with all applicable FCC equipment authorizations regulations, requirements and equipment functions
not associated with the transmitter module portion. compliance must be demonstrated to regulations for other transmitter components
within the host product; to requirements for unintentional radiators (Part 15B). To ensure compliance with all non-transmitter functions
the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. If a host was previously
authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module and a
module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues
